F3 Hits Mineralization within 8m of the

Athabasca Unconformity

Kelowna, British Columbia--(Newsfile Corp. - July 17, 2023) -

F3 Uranium Corp

(

TSXV: FUU

)

(

OTCQB: FUUF

) ("

F3

" or "

the Company

") is pleased to announce scintillometer results from four holes

of the ongoing 30-hole summer drill program at the JR Zone on the Patterson Lake North ("PLN")

Property, including 2 high grade intercepts in mineralized intervals that are both within

11m

of the

Athabasca Unconformity. Drill hole PLN23-073 tested for mineralization 15 meters up-dip of the high

grade intercept reported in PLN23-068 on line 060S (see NR July 4, 2023) and intersected

mineralization over an 11.5m interval starting

8m

below the unconformity, including 0.70m of high grade

(>10,000 cps), of which

0.50m was off-scale radioactivity (>65,535 cps) between 225.00m and

225.50m. Drill hole PLN23-074 on line 075S intersected 15.0m of mineralization starting

11m

below the

unconformity, including 0.20m of high grade (>10,000 cps) between 228.15 and 228.35m.

Raymond Ashley, President, commented:

"We are excited that basement mineralization has been intersected even closer to the Athabasca

Unconformity, now within 8m, as this reinforces the potential for an unconformity or sandstone

component to the JR Zone mineralization. The discovery of mineralization at the unconformity or in the

sandstone would provide a compelling new target for JR Zone expansion drilling. Tests up dip from the

JR Zone mineralization are ongoing to define the best possible target at the unconformity for this drill

program. The Shea Creek deposit 46km to the north of PLN and the Key Lake deposit on the east side

of the basin are examples where basement hosted uranium mineralization extends through the

unconformity and into the sandstone. The first step out hole on line 165S did not intersect mineralization

but additional drill holes are being planned on that section to continue to expand the footprint along strike

of the JR Zone basement mineralization.

In addition, exploration drilling along the A1 main shear zone

has commenced, and prospective targets will be tested."

Drilling Highlights:

PLN23-073

(line 060S):

11.5m

mineralization from 215.5m - 232.0m, including

0.70m

mineralization of >10,000 cps radioactivity between 225.00m - 225.70m including

0.50m off-scale radioactivity (> 65,535 cps)

between 225.00m and 225.50m

PLN23-074

(line 075S):

15.0m

mineralization from 225.0m - 240.0m, including

0.20m

of mineralization >10,000 cps between 228.15 and 228.35m

Drilling Intercepts:

PLN23-071

(line 165S):

No mineralization >300 cps

PLN23-072

(line 690S): Exploration Hole

No mineralization >300 cps

Natural gamma radiation in the drill core that is reported in this news release was measured in counts

per second (cps) using a handheld Radiation Solutions RS-125 scintillometer. The Company considers

greater than 300 cps on the handheld spectrometer as anomalous, >10,000 cps as high grade and

greater than 65,535 cps as off-scale. The reader is cautioned that scintillometer readings are not directly

or uniformly related to uranium grades of the rock sample measured and should be used only as a

preliminary indication of the presence of radioactive materials. Samples from the drill core are split in

half on site and are standardized at 0.5m lengths. One half of the split sample will be submitted to SRC

Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK. for

lithogeochemical analysis using their "Uranium Package".

All depth measurements reported are down-hole and true thickness are yet to be determined but the

Company estimates true thickness of the reported intervals in this news release to be close to reported

interval widths.
